Is there a way to prevent an IWorkbenchWindow from closing?

Question

So I have my IWorkbenchWiondow object, window.
I add this listener to it:

window.addPageListener(new IPageListener()
{
    @Override
    public void pageOpened(IWorkbenchPage page)
    {
        // method stub
    }

    /**
     * Whenever the user tries to close the workbench window, this method gets called.
     */
    @Override
    public void pageClosed(IWorkbenchPage page)
    {
        if (MessageDialog.openQuestion(page.getWorkbenchWindow().getShell(), "Question", "Do you really want to close the application?"))
        {
            // YES, then no problem, close
            return;
        }
        else
        {
            // NO
            System.out.println("Now what?");
        }
    }

    @Override
    public void pageActivated(IWorkbenchPage page)
    {
        // method stub
    }
});

How can I stop the window from closing if the user says No?
Or how can I achieve the same end result?

Caveat: I've only given this technique a minimal test and it appears to work as expected.

From the IWorkBenchWindow get an IWorkbench object.

Add an IWorkbenchListener to the workbench object.

The listener has a preShutdown method that should allow you to veto the close.
